I's Ashamed to admit it but I have done the exact same thing, when at work , I came in the receiving doors with the folks up a little, and went to park it on the loading dock, the sprinkler head was on a pipe that was hanging down... it hit the forks and I heard this God awful sound of twisting metal.. I got wet that day, the fork lift didn't work for a few days, I went home to change... I didn't however loose my job..
